LIST OF BIRDS OF CHEYENNE AND VICINITY. 
By Frank Bond. 
Cheyenne is located in the midst of the Great Plains region, a 
little over 6000 feet above the ocean, with an annual rainfall of 
thirteen inches. The plains around Cheyenne are drained by streams 
fringed by cottonwoods and willows which attract the migrants. 
One of these streams flows through the city, which by persistent 
arboriculture has been made an immense grove of trees, an oasis in 
the desert. Five small lakes, from within the city limits to a mile 
and a half beyond, offer resting places to waterfowl of all descrip¬ 
tions. The mountain range twenty miles west of the city, acting 
as a barrier to flight, completes the conditions which give Cheyenne 
a peculiar and diversified avifauna. The list covers a radius of about 
three miles from the city limits. 
JEchmophorus occidentals : Western Grebe. — Rare visitant. 
Colymbus holbcellii : Holboell Grebe. — Rare visitant. 
Colymbus nigricollis californicus: Eared Grebe. — Common during migra¬ 
tions. 
Gavia imber: Loon. — Not common but tolerably regular visitor during 
migrations.
